Description

TECHNICAL FIELD

[0002] Many alcohol preparation reactions are exothermic reactions, such as the hydration of olefins to prepare alcohol, the hydrogenation reduction of aldehydes or ketones to prepare alcohol, etc. A large amount of heat will be released during the reaction process. If not cooled in time, the temperature of the reaction system will rise rapidly. High temperature may cause the reaction rate to be too fast to control, and even may cause an uncontrolled reaction, leading to safety accidents. Therefore, a cooling device needs to be used for cooling treatment in actual use.
